Mathmos Light Charms for your cellphone
Turning your cellphone ringer off is a given whenever you enter a library, museum, cinema, or church, but more often than not we tend to miss out on calls as the vibration of the handset itself isn’t too strong by any means. The Mathmos Light Charms for your cellphone solves this problem, blinking crazily whenever there is an incoming call courtesy of radio frequency emissions. You can choose from a mini light bulb version or a mini lamp lava version in white, blue, or red colors. They retail for approximately $12 a pop. Be forewarned though – these can be rather blinding especially in a dark place like the cinema.
